1b citt whom 'it may concern.'

Be it known that l, .\.i.iii:ii a citizen oi" the United States, residing' :it St. Louis. Missouri, have invented a certain new and useful Improvement iii tai'-'l`i'ii'el s, ot' which the tollowiiie' is a t'ull, clear, and exact dcscrii-ition. such as will enable others skilled in .the artm-to which it, appei'taiiis to make and iise'the' saii'ie, reference being had to the :iccoiiipaiiying drawings, forming part I ot this specification'. in which l Figure l is a. side elevational view. partly in section7 ot' a cai' truck embodyingV the teatiires ol' in v invention; Fig. 2 is tin enlarged horizontal sectional view taken oi'i the line 9 of Fig. l; Fig. 3 .is a diagrainniatical Application filed 'February 1, 1909. Serial Noi 475,461.

shittinglatei'allywhcu inservice. lteinoi-zible tillcrbloclts t are interposed between the bolf the .springY seat. and the lillei' blocks are ll-ieii lilted out ol' the space between the bolster view illustrating'various positions occupied 4 by the bolster while iifis being i'eiiioved from Y the truck; Fig, -l is ay perspective view ot a portion of the bolster and tillei.' block shown in Fig. 1 andFig. v2; Fig. 5 illustrates a niodih'ed forni of the tillerblocl'ts shown in Fig. 4; Fig. -G is a perspective View of a modified ioini of bolster; Fig. T is a detail view of a filler block used in connection with the bolster shown in Fig. G; 4and Fig. 8 is a side elevational view. of a nioditied forni of the truck .shown in Fig. .l.

'lhis invention relates to iinproven'ients in cai' ti'uchs. the inaiii object. being to provide a ear truck iii which the. bolster can be easily removed t'roin the ti'iiclc side trames.

In the drawings indicates a truck side frame provided with columns l, the ends of said traine being n'ioiinted on Journal boxes 2.

2 indicates a tie bai' arranged under the. side frame and connected to the journal boxes. A bolster Il extends through an opening in the ti'uclt side and rests on springs 3. the latter being' supported by a spring seat `'t tioi'iiied integral with the truck side. 'l'he usual column guides 5. which ai'e preferably formed integral with the bolster, .operatc with columns l and preveiittlie bolster liijoin shitting' longitudinally.

'lhc end portions ot' the bolster which are located between columns l are prctei'ably rec,v

tangiilai' in cross section, the distance across said rectangular portion measured on the d iago-nal line l; being less tliaiilhe distance be,- tween cohiiniis. ',l`o obtain thesel relative dimensions, the bolster must be normally spaced a certain distance away' from thecoluninsand means must be provided for locking the, bolaiid columns. .\l'tei' the springs and tillei' bloelis have been i'eiiioved l'roin the ti'iielt. the bolster is turned :is shown by dotted lines in Fig. Il to the position indicated :it (l. and when the bolster is iii this latter position it :can be moved longitudinally through the sup-port. fillers (l.

ol'iening' in the truck .side trame. as thel column `:guides are then out. ot'l alineiiient willi the columns.

Fig. 5 illustrates a modified forni of tillei.' block having supporting lugs t5" 'which are adapted-to rest on the column guides of a bolster.

In the inodilicd loi'm shown in Fig. (l and Fig. the filler block t3" is supported by a lug 7 which is secured toitlie bolster. said lug` being"noriiiallv locatei'l iiiV a recess' S' Y t'orn'ied in theI lillenblocli t'i".

ltig. 8 illustrates an ordinary7 arch bai' or dian'iond f'an'ie truck embodying' the features of my invention. Vhile any ot' the tiller blocks herein described could be used on an arch bai' ti'iiclc, in. Fig'. 8 l have shown the Columns l provided with lugs 9 which lln this toriii. when the bolster 'll is dropped on the spring seat 10, the fillers G instead ol sliding down. with the bolster' fall toward they center ot' the ti'iiclt side franie.

` (.)ne advantage otl this invention is that it'.

allows metal liolstei's to he substituted for comparatively wide. Wooden holstersoii/oldV trucks without. altering' the structureA 0l. the side. t'i'aii'ics w...f\iu ithei' very desirable feat-uref-is-'that the removable filler blocks can be used to advantage in connection with "types of holsters and Side, Jframes which liereti'itore caused considerable 'time and labor to be spent. in assembling and diSinan.- lling the truck, which they formed part of.

sier against rotation and preventing' it. li'oin filari/ing thus described the invention7 what 2. In a ca'rttruck, side frames having columns, azvbolster spaced away from the inner faces pf said columns, column guides which coperate with said columns, said column esbeing rigidly secured to the bolster, and removable fillers interposed between said bolster and columns; substantially as described.

3. A car truck having side frames including columns, a bolster provided with columnguides which cooperate with said columns', said bolster being spaced away from the inner face of the columns, and removable fillers interposed between said bolster and columns; substantially as described.

4. A. car truck having side frames includ-` ing columns, a bolster provided with co1- umn guides which coperate with said col-- umns, said bolster being spaced away from the inner face of the columns, and removable llers interposed between said bolster' and columns, said fillers being supported by the bolster; substantially as described.

5. In'a car, truck, side frames having columns, a bolster spaced away from the inner faces of said columns, column guides which cooperate with said columns, said column guides'beingI formed integral with the bolster", and removable fillers loosely mounted between said bolster and columns; substantially as described.

6. A car truck having a side frame iny faces thereof, and removable fillers inter- A posed between said bolster and columns; substantially as described. y

7 Ina car truck, side frames having columns and a spring seat, a bolster having pairs ofcolumn guide-s .which `coperate with said columns, removablefillers interposed between said bolster and` columns,`

each of saidlillers being arranged between interposed between said' bolster and spring seat; substantially as described.f

In testimony whereof I hereunto affix my la pair of said column guides, and springs signature in the presencel of two witnesses,
